спасибо большое всем!Thank all of you!

• Lots of interesting talks and many promising results.

• The Priority Projects are reaching important milestones. – COSMO-DE-EPS becomes pre-operational shortly!

• Priority Projects (and also some of the Working Groups) are building up common know-how, and the project members obviously enjoy to reach common goals together.

• At last, COSMO starts to become a large family, and does indeed develop a common spirit.

Science Plan 2010-2014

What has been done since the last General Meeting:• submitted SP for an external review (SRNWP ETs and

COSMO-CLM; 7 reviews obtained)• addressed (most of the) questions, comments and

feedback by reviewers; did some structural and many editorial changes

main changes in content since last GM:• increased visibility of COSMO-CLM and COSMO-ART

to reflect their rising importance • added HP(2)C / PP POMPA issues

• Steering Committee approved the SP last Monday

Science Plan 2010-2014: Summary

Goal: Operational forecasting of mesoscale weather

Strategy

Ensemble prediction system for the convective scale

Data assimilation system for the convective scale

Extension of environmental prediction capabilities

Verification and validation tool for the convective scale

Intermediate resolution COSMO version for BCs

Usage of massively parallel computer platforms

Intensified collaboration

Science Plan: Next steps

• distribution to COSMO (and beyond) asap

• information of directors

• publication on COSMO web-site (public part!)

• update / next revision of Science Plan in roughly two years Science Plan 2012-2016

6 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, MoscowMarco Arpagaus (marco.arpagaus [at] meteoswiss.ch)

Science Plan: Consequences

• Establishment of a new Working Group “Predictability and Ensemble Methods” (WG 7)

• Working Group “Interpretation and Applications” (WG 4)• “Interpretation”: stronger focus on forecaster issues (‘how

to use the models’) and case studies (forecasters as very demanding and candid users of the models)

• “Applications”: explicit inclusion of post-processing methods (calibration, MOS, …; fieldextra)

• invitation of COSMO-ART (Bernhard Vogel) and new DWD COSMO Coordinator (Uli Blahak) to the Scientific Management Committee

Source code management for ‘COSMO Software’

Motivation:

• growing amount of software

• growing community contributing to the development of the software

‘COSMO Software’

A successful source code management needs

scientific planning

technical requirements

‘COSMO software’

Technical requirements for software to become

‘COSMO software’:

• portable

• documented (internal & external)

• supported

Consequence for software to remain ‘COSMO software’:

• continuous and long-term maintenance

9 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, MoscowMarco Arpagaus (marco.arpagaus [at] meteoswiss.ch)

‘COSMO software’

• COSMO model, including• forecast model• data assimilation system (nudging, ETKF filter)• provision of operational external parameters

(Note: EXTPAR will only be distributed for R&D and ‘as is’)• INT2LM

• fieldextra (COSMO post-processing tool)

• VERSUS (COSMO verification tool)

10 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, MoscowMarco Arpagaus (marco.arpagaus [at] meteoswiss.ch)

Source code management for ‘COSMO Software’

Scientific planning

• clear strategy• Science Plan• Priority Projects and Priority Tasks• yearly Work Plans

• clear responsibilities (inside COSMO) and focal points (outside of the consortium (e.g., COSMO-CLM, COSMO-ART))

11 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, MoscowMarco Arpagaus (marco.arpagaus [at] meteoswiss.ch)

Source code management for ‘COSMO Software’

Scientific Management Committee (SMC) is responsible

for the scientific planning related to (and needed for) the

source code management:

• release planning and priority setting

• definition of responsibilities (in accordance with resource planning by STC) and focal points (in accordance with respective planning by e.g., COSMO-CLM and COSMO-ART)

This transfers substantial responsibility (mainly) from

Ulrich Schättler / DWD to the SMC / COSMO!

Source code management for ‘COSMO Software’

Technical requirements

• clear rules• coding standards• documentation standards• quality control standards (test experiments, verification)

• transparency ( ‘redmine’, ‘codendi’, …)• release planning• setting of priorities
